盐沼

The nektons in an intertidal creek of a newly formed salt marsh at Yangtze River estuary were sampled by Fyke net to assess its habitat utilization of the salt marsh.

利用长袋网采集了长江口新生盐沼湿地潮沟内的游泳动物，分析了该类盐沼湿地的鱼类栖息地利用。

As a result, there was stable accumulation on the saltmarsh, compared to frequent alternation of erosion and accretion in adjacent mudflat.

研究区潮流不对称性明显，主要表现为涨潮优势，且由光滩向盐沼上部不断增强，潮沼植物和地形变化是加强盐沼区涨潮优势的主要原因。

But the salt marsh trend to be larger.2. The reducing of wetland also has the relation with human movement.

而盐沼湿地的面积却随着降水量的减少而增加，加之年平均气温的逐步升高，盐沼湿地的面积有扩大的趋势。

These results are consistent with the observation that the salt marsh plants often grew better near tidal creeks than in the inner areas.

这些模拟结果较好的吻合了潮沟附近较盐沼内部盐沼植物长势较好的现象。

However,there is no consistent paradigm that indicates which primary producer is the energy base of salt marsh food web,and the extent to which salt marsh supports the estuarine fishery production.

然而，对于哪类初级生产是盐沼湿地食物网的能量基础、以及盐沼湿地对河口及滨海渔业生产的支持程度，仍然没有一致的结论。

With the passage of time, species numbers of polychaeta increased (from 3 to 6) while species numbers and abundance of macrobenthos increased. A new pattern of macrobenthos was formed.

互花米草盐沼发育初期，大型底栖动物群落以腹足类为主，丰度和多样性较低，物种丰富度(d=2.18)和多样性(H′=2.19)均低于芦苇盐沼(d=2.61，H′=2.29)。

In addition,exotic C4 plant Spartina alterniflora is rapidly invading the salt marshes in the Yangtze River estuary,and displacing the native C3 vascular plants Phragmites australis and Scirpus mariqueter.It is no clear whether the C4 vascular plant invasion has serious impact on food web structure and trophic function of the salt marshes of the Yangtze River estuary.

另外，外来种互花米草正在快速入侵长江口盐沼湿地，这种C_4维管植物入侵将对盐沼湿地食物网及其营养功能会产生什么样的影响也是一个值得探讨的问题。

The results showed that the value of the district was the highest, which is 2.6 × 10^7 yuan RMB, when the areas of the ecosystem and prawn pond are 25.4 km^2 and 9.6 km^2 respectively. And that is recommended that ideal Spartina alterniflora/ pond ratios should not exceed 27% of the ecosystem area converted to ponds.

研究结果里示，当互花来草盐沼生态系统面积为25.4平方公里、对虾养殖面积为9.6平方公里，即对互花米草盐沼生态系统的开发面积不超过其总面积的27%时，可实现该区域资源价值的最大化，其评估值最高，为2 626.7万元。

The investigation of the complex flows and the associated solute transport in marsh soils is made in order to improve our understanding of these wetland systems, particularly the relation to the important hypotheses in the marsh ecology: the nutrient outwelling and the plant zonation.

目前国际上存在关于盐沼的两大假设：盐沼系统输出养分和盐沼植物带状分布。为验证这两大假设，增强对盐沼湿地的了解，盐沼孔隙水流动及溶质运移研究至关重要。

The tidal wetland sediment appeared the tendency of changing small from sea to land and from bottom to top.

结果表明，潮间带沉积物呈自海向陆和自下向上变细的趋势，一般光滩沉积物粒径〉50μm，盐沼上部沉积物粒径〈25μm；沿岸方向上，茂密盐沼的沉积物较之稀疏盐沼细；盐沼中的流速和波高较之相邻光滩减少50%以上；植物粘附悬沙干重达

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
